HOLLAND, MI -- About 18,000 gallons of untreated sewage overflowed from a public main in Holland Oct. 12, according to a release from the Holland Board of Public Works.

The BPW was notified of the overflow near 245 Fairbanks Ave. about 4:45 p.m. Friday. Crews corrected the overflow by 6 p.m.

Before crews could stop it, the overflow appeared to have occurred for one and a half hours at a rate of 200 gallons per minute.

The overflow was caused by a power issue at a sanitary sewer lift station, the BPW said. Sewage came out of a public manhole and entered a portion of the Maplewood Intercounty Drain, which ultimately flows into the Macatawa River.

Cleanup continued into the evening of Friday.

The Ottawa Health Department and the Michigan Department of Environmental Quality were notified.
